In the figure below , ABCD is a square . Points are chosen on each pair of adjacent sides of ABCD to form 4 congruent right tria

Lostsunrise [7]

Answer:

5/9 of the area of square ABCD is shaded

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

To find out what fraction of the area of square ABCD is shaded, divide the shaded area by the total area of square ABCD

step 1

Find out the area of square ABCD

The area of a square is

$A=b^{2}$

where

b is the length side of the square

we have

$b=(x+2x)=3x\ units$

$A=(3x)^{2}$

$A=9x^2\ units^{2}$

step 2

Find out the area of the 4 congruent right triangles

$A=4[\frac{1}{2}(x)(2x)]=4x^{2}\ units^2$

step 3

Find out the area of the shaded region

The area of the shaded region is equal to the area of square ABCD minus the area of the 4 congruent right triangles

$A=9x^2-4x^{2}=5x^{2}\ units^{2}$

step 4

Divide the shaded area by the total area of square ABCD

$\frac{5x^{2}}{9x^{2}} =\frac{5}{9}$

therefore

5/9 of the area of square ABCD is shaded
